Winterizing your RV is essential to prevent damage from freezing temperatures, but should you put antifreeze in your RV’s hot water tank? The short answer is no, and here’s why.
Why You Shouldn’t Put Antifreeze in the Hot Water Tank
🚫 Not Necessary – Most RV water heaters have a bypass system to prevent antifreeze from entering the tank. 🚫 Difficult to Rinse Out – Antifreeze can leave behind a residue and an unpleasant taste, making it harder to flush out when de-winterizing. 🚫 Potential Damage – Some types of antifreeze could react with the tank lining, leading to long-term issues.
Proper Steps for Winterizing Your RV Water System
- Drain the Water Heater – Turn off the heater, let it cool, then open the drain plug and pressure relief valve.
- Use the Bypass Valve – Most RVs have a built-in bypass valve to prevent antifreeze from filling the hot water tank. If your RV doesn’t have one, consider installing it.
- Pump Antifreeze into the Plumbing – Add RV-specific antifreeze to the freshwater system to protect pipes and fixtures.
- Run Faucets Until You See Pink – Open all faucets, including the shower and toilet, until pink antifreeze flows through.
Instead of putting antifreeze directly into your RV hot water tank, use the bypass system and focus on protecting your plumbing lines. This ensures a clean and hassle-free startup in the spring.
